| Research Abstract |
It is well-known that the traffic jam is understood by the idea of physics. Phase transition can explain why a state of traffic flow changes suddenly at a certain density. In pedestrian flow, so-called blocking occurs in a narrow corridor at high density. It can be understood in the same way as the traffic jam. In this work, we investigate phenomena in collective bio-motion by the same model as traffic and pedestrian flow. As a result, a meander which appears in a long group of organisms can be explained in a similar way.
